RESILIENT TIRE FOR WHEELS.

Application 'filed March 23, 1921.

To all 'whom it may concern.'

Be it known that we, Yunnan Rim), Ronnrur HannNnss REID, and lViLLLm' Een), Jr.. all subjects of the King of Great Britain and Ireland, and residents Vof Burnbanlr, Hamilton. Scotland. engineers. have invented certain new and useful Resilient Tires for lVIieels, of which the following is the specification.

The invention has for its object to provide for vehicle wheels a tire offering effective insulation from road shock.

A tire made according to the invention eomln'ises essentially a rim member preferably flexible, resilient. or defornnible, and preferably Arubber shod, Vand in combination therewith and arranged between this rim member and the wheel felloe. or an inner rim, a deformable or elastic member. This deformable member, which is in whole or in part of rubber, is of substantially crucitorm cross-section having diagonal arms. That is to say, it comprises a central part from which diverge four diagonal struts. The central part and the strutdilre parts may either be continuous or discontinuous. That is to say. these several part-s may be continuous webs extending around the whole periphery of the wheel, or any one or more of' them may be a series of separate struts, or pieces, severally interconnected into a continuous whole.

The outer ends of the outer diagonal arms of the crucform member are rigidly anchored to the outer rim member, while the outer ends of the inner diagonal arms are rigidly anchored to the wheel felloe or rim. lVhen these arms are in the form of series or struts, their outer ends may be connected by a continuous ring. In some cases struts of rubber may be arranged between substantially the points of anchorage of the inner and outer arms.

The structure of the cruciform member may be re-enforced by strips or the like of `metal, or of textile fabric embedded in or applied to its parts.

In order to exclude dust and moisture, annular coverings of fiexible material, for example rubber, may be applied between the rim member andthe Wheel felloe or rim proper, or the whole wheel may be enclosed between discs of such material.

A series of examples of the improved resilient tire is shown on two accompanying Specification of Letters Patent.

sheets of explanatory drawings, Figures l, 3 and 5, Sheet l, being` transverse sections of' three examples. while Figures 2, `land are ycorresponding part side elevations. Figures T, and 9` Sheet 2, are transverse sections of three further examples, and Figures 9, l() and ll respectively, a transverse section. a part side elevation and a plan partly sectional of another example.

lt is to be understood that the various subintegers (as they may be called) such as the form of rim. the method of anchorage. the manner of re-enforcing, are interchangeable throughout the examples which are only given by way of illustration and not as exhaustive of the modification to which the tire may be subject, without departing from the essence of the invention.

The example shown in Figures l and Z is typical of a deformable member of pure crucilorin section, the continuous diagonal arms A of which merge in a central continuous member B where they approach one another and in continuousouter parts C by which they are anchored respectively to the outer rim member D and to the inner rim proper E, the means of ancho age being in each case a series of washered bolts G.

In this example the outer rim member D is comparatively inflexible, and upon it there is mounted a solid rubber tire H. The rim proper E is mounted upon the usual felloe J of a wooden wheel. Annular coverings K of flexible mate-rial such as rubber are fixed upon the outer faces of the outer parts C for the purpose of' excluding dust and moisture.

The example shown in Figures 3 and 4 only differs from that just described in that there is provided between the inner and outer diagonal arms A on each side of the central member a series of radial struts L.

That shown in Figures 5 and 6 again differs from either of the two foregoing examples (with either of which it may be combined) in that a series of transverse apertures M is pierced in the central member B at the base of the arms A. Alternatively, or in addition, there may be similar radial apertures N as indicated by dotted lines in Figure 5. Also, as indicated by dotted lines, a recess O may be formed around the inner periphery.

In Vthe example shown in Figures 3 and 4 the outer rim member D is shown as resiliently built up of a series of strips P which may be of fabric or of a flexible material such as steel, or of a combination of these encased in rubber. In the example shown in Figures 5 and G the rini member D isV afsingle element either of rigid or of iiexible, resilient, or deformable material.

VThe example shown in Figure '7 diEers from that Vshown in Figures 1 and 2 in thatl there is in the central member B an axial aperture A tube S may be linserted between the outer part of the member B and a recess formed in the inner part of an outer tire II, as in Figure 8, which tire is formed with integral lateral webs D on whichv it is carried and which are re-enforced by internal flexible, resilient, or deformable members F near its edges, there being a similar strip T in each of the outer members C. It will be seen that the examples shown in Figure 8 is of the type shown in Figuresv 3 and 4 and in which there is a series of radial struts L, these struts in the vpresent instances not extending out to the be widely varied without departing from its essence, more particularly inY the matter of the manner of anchoring the parts C, the manner of applying and the form of constructionA of the outer rim member D, the form of the inner rim member E, the type of wheel to which the tire is applied and the details generally.

What we claim iszl. In a wheel, a substantially rigid wheel periphery, a rim element surrounding and spaced therefrom, in combination with an interposed resilient cushioning member of substantially oruciform section and comprising a central part spaced from the wheel periphery and rim clement, `and divergent struts extending outwardly and inwardly therefrom on opposite sides of said central part and in directions atangles to the plane of the wheel, the outer ends of said struts affording outer and inner points of contact and support for said cushioning member with respect to said wheel periphery and surrounding rim elements, substantially as set forth. f

2. In the Structure set forth in claim l, discontinuous strut members.

3. In the construction specified in claim l, a flexible rim element.

In testimony whereof we have signed our names to this specification.
